On December 9, construction of a nearly 275-ton official ship began in Danjiangkou City. Don't look at the tonnage of this ship is unremarkable, but in fact, it has caused quite a stir, because this ship is pure electric!
The ship has a total length of 35.32 meters, a width of 8 meters, a depth of 2.5 meters, a design draft of 1.25 meters, and a wind resistance level of 6. The main hull adopts a single-bottom, single-deck transverse skeleton steel welded structure, and the superstructure is a longitudinal skeleton aluminum alloy welded structure. Its completion will fill the gap of clean energy powered ships in the Danjiangkou reservoir area. In addition, the ship adopts lithium iron phosphate battery power drive, double rudder propeller propulsion, equipped with a variety of anti-pollution measures, "zero pollution, zero emission, no noise, low vibration", will accelerate the high-quality development and transformation of the follow-up project of the South-to-North Water Diversion Project and effectively promote the green ecological construction of the Han River.
Since the ship is designed as the first new energy pure electric ship in the Danjiangkou reservoir area, the challenge to the entire system is very large, and the whole ship power system, rudder system, propulsion system, power distribution system, auxiliary system and network communication system put forward very high requirements; the ship uses an AC and DC dual power distribution system, sets up 12 lithium battery clusters to power the whole ship's electric propulsion system and specific electrical equipment, power motors 200KW2 units, lithium battery total capacity of about 1676kWh, endurance time of 6 hours, Many of its advantages make it an emerging technology in the field of official ships, which is expected to be completed and delivered in April 2022.
